Yes, 35 is a rational number. A rational number is defined as any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
In this case, 35 can be expressed as:
\[ \frac{35}{1} \]
Here, 35 is the numerator (an integer), and 1 is the denominator (also an integer and not zero). Because it can be written in this form, 35 qualifies as a rational number.
